SECIFICATION vforming part of Letters Patent No. 410,825, dated September 10, 1889.

Application led December 27, 1888. Serial No. 294,779. (No model.)

T all whom it may concern:

Beit known that I, JOHN MURRAY DUR- WARD, residing at Bristol, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Clock-Cases; and I do declare the following to be a full, clear, and exact description of the same, reference being' had to the accompanying drawings which form a part of this 1o specification.

My invention relates to an improvement in cases for the class of clocks known to the trade as French marble clocks, the object being to effect an economy of labor and material in their construction and to produce a more durable article.

IVith these ends in view my invention consists in a sectional stone clock-case having its several parts bolted and keyed together,

2o and in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view in front elevation of .a clock-ease embodying my invention. Fig. 2 is a view thereof in vertical longitudinal section. Fig. 3 is a detached plan view of the body or the central part of the case. Fig. 4 is a detached reverse plan view of the base of the case with go one end of the base-frame in horizontal section. Fig. 5 is a View of the clock-base in vertical longitudinal section on the line a h of Fig. l. Fig. 6 is an enlarged broken sectional view showing one of the bolts. Fig. 7 is a de- 3 5 tached view, in side elevation, of one of the bolts together with its nut and pin 5 an d Fig. S is an enlarged broken perspective view showing one of the blind pockets Qin the back piece Il of the base-frame.

My invention maybe applied to the construction of stone clocks, whether the material be marble, onyx, slate, or other variety of stone and whatever be the design of the case. The bolts and keys will only change in position, not in principle.

For the purposes of illustration I have herein shown my invention as applied to a clockcasc made of slate finished in imitation of marble. It has a body consisting of a square 5o frame composed of four sla-bs A and of two wings or extensions, each composed of two blocks B and a slab C. The said extensions are respectively applied to the ends of the frame, which extend an equal distance above and below them to form spaces for the trans- 5 5 verse moldings I), the outer faces of which are iiush with the upper and lower edges of the frame. A dat slab E, having its edges molded, rests upon the upper edge of the frame and upon the two upper moldings D and forms 6o the top of the case. Thelower edge of the frame and the lower moldings rest upon a base-slab F, which is itself secured to an oblong base-frame composed of a front piece G and a similar back piece H, like end pieces 6 5 I I, and binding-blocks J J, the latter being located with the said pieces and respectively situated at the opposite ends of the baseframe, which, together with the base-slab, forms the base of the case. The base-slab F 7o is attached to the said blocks by bolts K, having their upper ends headed and their lower vends threaded to receive nuts L, screwed against the lower faces of the blocks.

The several pieces composing the said body 7 5 and base-frame are secured together by means of bolts M and keys N. For convenience I will describe the application of the bolts and keys to the construction of the base-frame, which, as illustrated in the drawings, best 8o shows them.

The inner edges of each of the bindingblocks are cut away to form three bearingfaces O, of which two are opposite each other, the other face being located within,between, and at right angles to the said opposite faces.

A hole P leads from each of the said faces through the adjacent parallel outer edge of the block. The base-pieces have blind pockets Q formed in their inner faces and located 9o so that when the parts are properly assembled they virtually form extensions of the holes P aforesaid. Each of these pockets Q is intersect-ed at a right angle by an opening R, extending inward frorn one edge of the piece in which it is formed. Bolts M, each threaded at one end, as at T, and .having a perforation U at the other end, extend through the holes P in the binding-blocks and into the aligned pockets Q in the base-pieces, in which they 10o are held by pins V, located in the intersecting openings R and extending through the holes in the bolt-s, the opposite ends of which are provided with nuts W, which are screwed up against the bearing-faces of thel blocks, whereby the base-pieces and blocks are solidly bound together. Preferably, and as herein shown, the openings R are filled in with molten metal, which sets and forms a binding X for the pins, holding them in place and reenforcing the structure. One end of each of the said bolts is thus iirmly embedded in a part offjthe case-structure.

For further binding the base-pieces together their adjacent ends have vertical pockets Y and intersecting horizontal pockets Z drilled 1n them. These pockets are arranged so that when the base-pieces are properly assembled the horizontal pockets in vone piece will communicate at an angle with the corresponding horlzontal pockets in the adjacent base-piece, whereby molten metal poured into one of the yerticalpockets will flow through its intersectlng horizontal pocket into the corresponding communicating pocket, and thence into the l vertical pocket by which that is intersected.

When this metal sets, it forms a key N, iirmly locking the ends containing it together.y v

If desired, wires or pins vmay be placed in f the pockets for imparting additional strength to the metallic key' so formed. TheV base-frame above described consti"- tutesa composite shell, the component part's of which the binding-blocks assist in securing together. f The; bolts and keys employed in constructing the body of the case are the same in principle as those described, their application being only different in the shape and arrangement of the parts.

It will befreadily understood from the foregoing description and from the illustrations given that these means may be applied in the `construction of any sectional case without regard to the design thereof.

The top, body, moldings, and base of the c ase are securely held together by means of two 1vertical rods A ,having their upper ends headed and inserted into shallow pockets B', formed in the lower face of the top of the case and filled. with metal Cvfor securing the rods in place. These rods pass throughholes D, formed in the upper molding D,through the spaces-E (see Fig. 3,) inclosed by the eX- tensions of the body through holes F formed in the lower moldings D D, and through holes G', formed in the base-slab, which, as has'been explained, is secured to the base-frame. The extreme vlower ends of the rods are threaded to receive nuts H', which are screwed against the lowerface of the slab, wherebyv the said sounding-board I', as shown b Fi". 2 of the drawings. This sounding-boardV carries the gong (not shown) of the clock.

The body and base of the clock-case form, as it were, compound transverse case-sections, and the top and base slabs and the moldings simple transverse case-sections, such slmple and compound sections being held together by vertical bolts. i

By making a clock-case as described a very fine case is secured without the use of the amount of material required for this 'class of cases as ordinarily constructed by binding the parts together by overlapping and ce- .men ting them, whereby economy of material and labor is secured. The several parts of the case being positively secured together by bolts and keys, the case is very durable and will not come to pieces under the vaction of moisture and heat, whereas cases made in the old way,- with cement and pitch, are, always coming to pieces. Being `lighter than the ordinary stone clock-case, they are easier to handle and' less expensive to transport.- Further-more, the parts being held together by bolts and metallic keys are so solid in their relations one to another that the case has virtually the property of a single 'piece of stone and gives al fine eifect to the bell or gong with which it may be supplied.

It is apparent that in carrying out in y 1nvention some changes from Vthe y' particular forms herein shown and described maybe made. Iwould therefore have it understood that I do not limit myself to such forms, but hold myself at liberty to make such changes and alterations as fairly fall within thev spirlt and scope of my invention. 'y y Having fully described my invention, what I claimas new, and desire to secure byLetters Patent, isl 1. In a sectional stone clock-case, the co'mbination, with a section provided with a blind pocket formed in its inner face' and with an opening intersecting the said pocket at an angle, of a bolt having one end perforated and inserted into the said blind pocket and a pin located in the said openin g and passing through the perforation in the bolt, substantially as set forth'. I Y' 2. In a sectional stone clock-case, the combination, with a stone section provided with a blind pocket formed in its 'inner face and with anv opening intersecting the said pocket at an angle, of a bolt having one end perforated and inserted into the blind pocket, a pin located inthe said opening and 'passing through the perforation in the bolt, and a filling located in the opening andkeying the pin in place, substantially asset forth. f

3. In a base for a stone clock-case, the combination, with a front piece, aback piece, and two end pieces, of two binding-blocks located vwithin and at opposite ends of the shell formed by the said pieces, andv each having its' inner face cut away to form three `bearing-i'aces, and three bolts carried by each block, having IOO IIO
